With the power improvement and technical advancement of ultraviolet LEDs, the lower-power ultraviolet mercury lamps have been gradually replaced by the advantages of long life and small volume in the market.
After the international ban on mercury (mercury), the Minamata Convention on Mercury was signed in 2013, there are only three years left until 2020, when mercury is completely banned.
In Japan, China, the European Union and other markets, in the field of ultraviolet lamps for household and industrial use, UV LEDs are needed to replace these UV mercury tubes, and it has also accelerated the take-off of the UV LED market around the world.
At present, the ultraviolet mercury tube used in the industry is generally used in the curing of various materials and processes related to plastics, as well as various life and industrial applications such as medical treatment, water purification, air purification, and printing.
With the development of UV LED in the industry for many years, power has been increased in recent years, and UV rays in different wavelengths such as UVA, UVB, and UVC have progressed considerably.
Taking the printing industry as an example, the ultraviolet mercury tube in the printing machine has a shorter life than the UV LED module. Therefore, the new model has been changed to a longer life, which can reduce the UV LED module for replacing the lamp tube and cure the ink. Reduce energy consumption, control of calorific value, and more.
In addition, medical and water purification fields have been introduced, and appropriate UV LED modules have been introduced. As for industrial high-wattage mercury UV lamps, the current UV LED power is still far from such products, and there is still a lot of room to play.
With the reshuffle of the general lighting field in 2016, the focus of major companies in 2017 began to shift to the sub-segment. It is estimated that the market value of UVC LED sterilization and purification applications in 2016 will reach 28 million US dollars, and will reach 257 million US dollars in 2021, with a compound annual growth rate of 56%.
In the first half of the year, LG Innotet announced the mass production of UV LED modules to perfectly sterilize the inside of the water purifier faucet. Allow customers to drink the water in the water purifier more confidently.
Since the end of last month, LG Inopo's business office has officially mass-produced the "UV LED module for water purifier faucet sterilization". In the new model of the "PuriCare Slim Updown" LG Electronics Drinking Water Purifier, which was launched on the 27th, the module has been installed.
LG Innotet announced the development of the world's first 280nm UV-C LED with an ultraviolet power of 70mW. At the same time, it has LED-related production systems such as wafers, chips, packages, and modules, which can be stably supplied to products.
In addition to 280nm UV-C LED for sterilization, LG Innotet also ensures the best product lineup for various applications such as 365nm, 385nm, 395nm, 405nm UV-A LED and biomedical 305nm UV-B LED for general industrial use. .
At present, the UV LED power on the market is not high enough. This is naturally limited by many technical methods for producing UV LEDs. However, Nikkiso has already developed a 50mW product in mass production, with the goal of achieving UV LEDs of 100mW specifications.
Low-power UV LEDs are used to analyze chemical elements, DOM Monitor, etc., while products from 10mW to 30mW are small-flow sterilization and purification, whether for water treatment or air purification. To be more than 30mW, to the 50mW stage of the product, it is suitable for medium-flow sterilization and purification, as well as resin curing applications.
Up to 50 mW to 100 mW, this UV LED is suitable for high-flow sterilization and purification, high-speed resin hardening and medical robot applications. At present, these application fields are still the world of high-voltage UV lamps, and UV LEDs are difficult to cut in. The main reason is that the power is not enough.
The current technology of Nikkiso has upgraded the specification of standard products from 30mW to 45mW. In the case of forward voltage and 6V, the efficiency of UV ultraviolet light extraction has been successfully improved, and the thermal resistance value is also from 15K/W. It becomes 7K/W.
Compared with the competition of mercury lamps, UV LEDs are of course less efficient than UV mercury lamps. However, UV LEDs have a fast response speed and do not require a heat engine. Therefore, the overall device efficiency is of course better. In the future, as long as the power can be increased, The range of applications is wider.
With the current technical capabilities of Japanese machines and the orders and demands received from market customers, the future potential in this area is worth looking forward to.
Asahi Kasei has made considerable progress in material science and industry experience. Their 2-inch AIN single-crystal substrate allows UV LEDs to be used together. Based on factors such as absorption rate, UV LED can be improved.
In addition, in order to create newer Blu-ray and UV LEDs, Toyota Synthetic has purchased new MOCVD-related module equipment from German manufacturer AIXTRON. The device is a reinforced 5x4 inch CRIUS Close Coupled Showerhead (CCS) system that creates blue LEDs and deep UV LEDs and is expected to be delivered to Toyota Synthetic in the first half of 2017.
Stator and rotor laminations are an important part of motors and generators. For small-size and large batch laminations, we usually use the progressive punching. The advantage of progressive punching is that it can be mass-produced in a short time. But the cost of the progressive punching die is high and manufacturing period of progressive punching die is long. Usually the outer diameter is under 300mm.
